About XLSX
XLSX is Microsoft Excel's spreadsheet format, storing rows, columns, formulas, and formatting in a compressed XML archive.
The standard choice for budgets, data tables, and anything requiring formulas or multiple sheets.
A single XLSX sheet can hold over 1 million rows and more than 16,000 columns.
💡 Excel's grid limit was only 65,536 rows until 2007. The modern 1,048,576-row limit is exactly 2^20.
About HTML
HTML (HyperText Markup Language) structures content for the web using tags, letting browsers render text, images, and links.
Useful for web pages, email templates, and content meant to be viewed in a browser rather than printed.
HTML was invented by Tim Berners-Lee in 1991 and originally had just 18 tags.
💡 The current HTML5 specification has grown to include over 100 elements, more than five times the original count.
